ffmpeg MAMP“dyld：未加载库”错误

本文介绍了ffmpeg MAMP“dyld：未加载库”错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在通过PHP的 exec（）命令在MAMP中的Mac OSX 10.7.3上使用ffmpeg，我有一个绝对路径设置为调用ffmpeg，例如

/ opt / local / bin / ffmpeg -i/sample.avi

但是我收到以下错误 -

dyld：库不加载：/opt/local/lib/libjpeg.8.dylib参考自：/opt/local/lib/libopenjpeg.1.dylib原因：不兼容的库版本：libopenjpeg.1.dylib需要版本13.0.0或更高版本，但libJPEG .dylib提供版本12.0.0

NB ffmpeg是通过Macports安装的。

它可以从命令行工作。

该怎么办？ >

编辑

我已经重新打开了 - 原来以为 shell_exec （）解决了这个问题，但实际上应该有所不同 - 直到今天进一步调查才明白。这是我的代码使用shell_exec并仍然给出上面的错误：

$ cmd ='/ opt / local / bin / ffmpeg - H'; $ cmd = escapeshellcmd（$ cmd）。 '2>& 1'; $ output = shell_exec（$ cmd）; var_dump（$ output）;

解决方案

问题是DYLD_LIBRARY_PATH设置为MAMP，我已经通过macports安装了ffmpeg。

这可能不是最好的修复，但现在我已经开始运行：

在 / Applications / MAMP / Library / bin / envvars 文件中，并注释如下行：

$ b $ $ b $ / code code code code pre>

并重新启动Apache

I am using ffmpeg on Mac OSX 10.7.3 in MAMP through PHP's exec() command, I have an absolute path set to call ffmpeg, e.g.

/opt/local/bin/ffmpeg -i "/sample.avi"

But I receive the following error -

dyld: Library not loaded: /opt/local/lib/libjpeg.8.dylib Referenced from: /opt/local/lib/libopenjpeg.1.dylib Reason: Incompatible library version: libopenjpeg.1.dylib requires version 13.0.0 or later, but libJPEG.dylib provides version 12.0.0

N.B. ffmpeg was installed through Macports.

It works from the command line.

What to do?

EDIT

I've reopened this - originally thought shell_exec() solved the issue, but infact it should be called differently - and I didn't realise until investigating further today. Here is my code using shell_exec and still giving the error above:

$cmd = '/opt/local/bin/ffmpeg -h'; $cmd = escapeshellcmd($cmd) . ' 2>&1'; $output = shell_exec($cmd); var_dump($output);

解决方案

The problem is that the DYLD_LIBRARY_PATH is set in MAMP and I've installed ffmpeg via macports.

This might not be the best fix but it has me up and running for now:

In the /Applications/MAMP/Library/bin/envvars file and comment the following lines as below:

#DYLD_LIBRARY_PATH="/Applications/MAMP/Library/lib:$DYLD_LIBRARY_PATH" #export DYLD_LIBRARY_PATH

and restart Apache
